Aluminum has tremendous work strength and will survive a good deal of impact
with only a dent. My son insisted on using our Grumman 15' canoe for white
water river running and the conclusion of every weekend was punctuated by the
noise of his rubber mallet pounding out the dents. He did succeed in inflicting a
small tear in the aluminum when the canoe came down heavily on a sharply
pointed rock but that was repaired by a local aluminum welder for a few bucks.
Small aluminum boats are noisy, cold, and eventually get an unsightly patina but
they sure are indestructible in normal use.
Incidentally, there is an abandoned Grumman Widgeon amphibian airplane in a
field adjacent to the Hudson River. The area was an old seaplane landing. The
plexiglass window is shattered, the tires rotted, the engine covered with
corrosion but the 50 year old aluminum airframe and hull look in good condition.
Any airplane restoration zealots out there?
